  1. Values are presented as mean ± SD, categorical variables are presented in frequencies (percentage)· Abbreviations: NRT = nicotine replacement therapy, BMI = Body mass index, FTND = Fagerstrom test for nicotine dependence, Definition: Bidi = Hand rolled cigarettes containing tobacco wrapped in a tendu or temburni leaf, Smoking pack year = (Number of bidi/cigarette smoked per day × Number of years smoked)/20 (1 pack has 20 cigarettes/bidis) TBscore = validated, composite marker of tuberculosis related clinical outcome· Difference in various parameters between the two arms were not statistically significant.
